You can often hear that good fans are an extra player, and I think that is the case sometimes. Fans can be that extra incentive for players to do their best and "leave their hearts on the field". But that is only one factor that may or may not be important, it is much more important that the team is good, in full form, and in a full lineup without injured players.
I saw this new system and I don't know what to think about it. It looks interesting at first glance, but we will see how it will look in reality... It might be interesting for fans from these countries to be able to attend various games, but it might be too tiring for the players.
